int nvme_dev_self_test (struct nvme_dev_self_test_args *args );
struct nvme_dev_self_test argument structure
The Device Self-test command starts a device self-test operation or abort a device self-test operation. A device self-test operation is a diagnostic testing sequence that tests the integrity and functionality of the controller and may include testing of the media associated with namespaces. The controller may return a response to this command immediately while running the self-test in the background.
Set the 'nsid' field to 0 to not include namepsaces in the test. Set to 0xffffffff to test all namespaces. All other values tests a specific namespace, if present.
The nvme command status if a response was received (see enum nvme_status_field) or -1 with errno set otherwise.
